I think that because they directly show the videos, it forces a reply from you which gives them better data to make recommendations. On other platforms like YouTube for example, there are a lot of factors beyond the video itself that influences if a person even clicks on it (like the thumbnail, the title, the number of views, who the creator is), so if someone doesn't click on a video, that doesn't tell you if they would have liked it or not. Because of that your data to make recommendations isn't as accurate. That's the main difference I see with TikTok. They make recommendations proactively, instead of reactively.
